STOP Analysis

Background Consistent behavior of high-performance optical structures requires maintenance of structural stability over the range of potential operating conditions. In practice, thermally induced aberrations are ubiquitous in optical systems and can limit the performance of optical devices such as gravitational wave detectors, deformable mirrors, lithographic systems, high power lasers, space optical instruments and telescopes, optical […]

Temperature-Dependent Coefficients of Thermal Expansion

Making accurate physics predictions using simulations requires a knowledge of the material properties and how to implement them correctly in the software. This is particularly important in analyses involving thermal expansion when the coefficients of thermal expansion (CTEs) of the materials vary significantly with temperature. For example, optical devices that operate in the vacuum of
